National Harmonised Traffic Counts

The Harmonised Traffic Counts dataset reports on the number and type of vehicles travelling past traffic counter stations across Australia in a given duration, over time. Depending on the sophistication of the counter and the provider, counts can be by vehicle classification (using the AustRoads 1-12 classification), a 2 or 4-level grouping of the 12-level classification or a simple count of all traffic. 

The data is sourced from a number of providers, either state authorities or commercial data collection facilitators, who publish open traffic counts. Count observations can be hourly, by calendar year or financial year – this depends on what each jurisdiction releases.

The NFDH is piloting the harmonisation and release of this data set, and has combined traffic count information from the following states: NSW, QLD, SA, TAS, and VIC. The extracts linked below are only samples of the full harmonised data set.
